Oh stop being a paranoid dipshit. HEPA filters are well understood, aren't made by this guy, and have been being tested by hospitals for fourty years.

"OMFG he claims a hepa filter does what hepa filters do??!!?!? WHY SHOULD WE BELIEVE IT"

Because it's pretty obviously a sensible claim. Duh. Go to Target, spend the $20 it would take to try it yourself, and please grow up a little bit.

I mean seriously, what kind of person thinks putting an air filter in front of a fan doesn't actually filter air? Seriously.

I think you didn't get the parent. Before the disaster, you screen the people who will be affected by it and designate the survivors. Those people get tags to be easily spotted and identified. Thus you can rescue the survivors easily and don't need to waste time on people not deemed worthy to be alive.

Even if I get spam that claims to be from my bank, I can see it being spam because I got similar spam allegedly from other banks I never did business with. The same with the two messages of unclear status, I seem to have with so many sites, that the one that claimed to have sent by a site I actually have an account with was easily spotted.

The quickest numbers I could find say that at the scales of large power-plants, the generator is very efficient, but the turbine not so much, around 50%. This would put the system as a whole at around 40% efficency sunlight -> electricity. That's competitive with the best solar voltaic systems tested in the lab, and 50-100% better than practical systems on the market. Assuming their system really does scale up to power plant sizes, of course.

Every institution abuses their power. Governments are just the scape goats U.S. Americans like to butcher. Other countries have banks, other big corporations or the neighbouring country to beat at. Stop blaming the government for all failures, or at least start distributing your blame more fairly.

In the late 1980ies, the Nuclear Research Facility at Rossendorf near Dresden, Germany had two Amigas 2000 as central processing units for their accelerator experiments. It was fascinating, because Rossendorf was in communist East Germany, and the Amigas probably were bought half-legally for obscene amounts of (east german) money. But appearently they urgently needed the 32bit processing capability and were using selfdeveloped Zorro cards for the signal reception and processing.

I've never understood how they were able to launch from the moon back towards Earth. Launching from the Earth requires massive infrastructure and huge rockets. Yes, the moon's gravity well is shallower, but still significant.

It's because the fundamental equation that relates a rocket's performance and the mass fuel it requires to orbital velocities is exponential. This makes it work out so that any chemical rocket leaving earth has to have the vast majority of its weight as fuel, where as a rocket leaving the moon only about half of its weight as fuel.

What's more, the entire lunar module and its fuel supply is dead weight as far as the earth launch is concerned, which makes the earth rocket and its fuel multiple all the bigger. Then there's the issue of bringing along enough fuel to slow down the craft into lunar orbit, and escaping lunar orbit back to earth. The lunar lander didn't need to handle any of that, either.
